Rift Protocol-Based Network Logical Layering Method and Device, Network Device and Storage Medium

3. The method of claim 1, wherein, in response to that the source device supports other topologies in addition to a default topology, the LIE packet carries a topology ID of at least one of the other topologies supported by the source device.

4. The method of claim 1, wherein the TIE packet comprises a Node TIE packet and a Prefix TIE packet; and the Node TIE packet comprises the neighbor information carrying the target topology ID, and the Node TIE packet and the Prefix TIE packet comprise the Metric information carrying the target topology ID.

8. The method of claim 6, wherein at least two topologies exist in the network; the LIE packet further comprises a topology ID of at least one topology supported by the source device which sends the LIE packet, the TIE packet comprises the neighbor information carrying a target topology ID and the Metric information carrying the target topology ID, and the target topology ID is the topology ID indicated by the LIE packet corresponding to the TIE packet.

10. The method of claim 8, wherein the TIE packet comprises a Node TIE packet and a Prefix TIE packet; and the Node TIE packet comprises the neighbor information carrying the target topology ID, and the Node TIE packet and the Prefix TIE packet comprise the Metric information carrying the target topology ID.

12. A non-transitory computer-readable storage medium having a first network logical layering program stored thereon, wherein the first network logical layering program is capable of being executed by one or more processors to perform the RIFT protocol-based network logical layering method of claim 1.

14. A non-transitory computer-readable storage medium having a second network logical layering program stored thereon, wherein the second network logical layering program is capable of being executed by one or more processors to perform the RIFT protocol-based network logical layering method of claim 6.
